OVERVIEW
The 3Com
®
Switch S7900E family is the next
generation of modern multilayer switches that meet
the evolving needs of integrated service networks.
The S7900E family consists of six chassis models:
S7910E (12 slots), S7906E (8 slots), S7906E-V
(8 vertical slots), S7903E (5 slots), S7902E (4 slots)
and S7903E-S (3 slots).
The platform uses modern ASICs and high speed
backplanes for long term investment protection.
All models have passive backplanes and support load
sharing and redundant management and fabrics for
high availability (except the S7903E-S with a single
fabric for cost-effective solution). The S7900E can be
deployed in multiple network environments, such as;
enterprise LAN core, aggregation and wiring closet
edge as well convergence and edge of Metropolitan
Area Networks (MANs), The S7900E provides the
latest distributed ASIC switching technology enabling
wire-speed Layer 2 and Layer 3 routing services for
the most demanding applications.
The S7900E supports high reliability technologies
such as non-stop forwarding (NSF), and ring network
protection. By improving productivity and ensuring
maximum up time, the S7900E can reduce total cost of
ownership (TCO). The S7900E family is environmentally
friendly, meeting the Restriction of the Use of Certain
Hazardous Substances in Electrical and Electronic
Equipment (RoHS) standards.
KEY BENEFITS
MODERN ARCHITECTURE
The S7900E chassis has been designed to allow for
long term investment protection. The backplane
traces will allow for higher performance in the future.
Intelligent power and environmental management
make these changes possible. The system uses a new
generation of more energy efficient merchant silicon,
with future support for emerging standards. This will
allow the implementation of new features in the
future, as they become available. With a choice of six
different chassis, users have increased configuration
flexibility. Fabrics and modules can be used across all
chassis.
EXTENSIVE FEATURE LIST
The S7900E provides all the features expected in a high
end modular chassis used for demanding enterprise
core, distribution and aggregation applications. It
supports wire-speed communications at layer 2 and
for IPv4 and IPv6 as well as MPLS services.
› Separate data and control paths for added security
and performance
› Extensive Quality of Service (QoS) features for
mission critical applications including Voice over IP
(VoIP), storage and video
› Comprehensive security for network access control,
encryption and protection of corporate resources.
> Extensive high availability capabilities and the ability
to create a resilient virtual switching fabric using
IRF™ (Intelligent Resilient Framework) technology.
